ADSP-2192 Peripheral Device Control Registers
• The function's
• The function's
GWAKE is an alias of the function's
when any of the conditions occurs which would set
function, according to the masks in the function's Function Power Man-
agement register (
the function's Function Event Force register sets the
PME_Status bit) for that function to 1.
The INTA Signal
In CardBus systems, assertion of the
master interrupt mask bit, in addition to the other interrupt control regis-
ters on the ADSP-2192. The

The pin is asserted under the following conditions:
• The function's
• The function's
INTRE
is set when any of the conditions occurs which would cause
asserted in PCI systems, according to the settings in the PCI Interrupt
Register. All three functions are controlled by the same interrupt-detect
signal. Additionally, writing a 1 to the
Event Force register sets that function's
INTRM
bit is set, the
way for an individual function to set its
rupt independently of the other functions.
